On the following tutorial we will explain how you can "CNC" a 2D DXF or SVG design. To be more specific we will generate GCode from a 2D design in order to CNC a 6000 bearing housing out of HDPE.
The tutorial's design is in .SVG format but it could be .DXF as well. To generate the GCode we will use ESTLCam and to send the GCode to our machine we will use the SourceRabbit GCode Sender.
In the "Open" window browse and select the 2D DXF or SVG file you want to CNC and the click the "Open" button.
ESTLCam now asks you to choose the appropriate measurement unit for your design. In our case we choose "Milimeters" and then we click the "OK" button.
This moment you are able to see your design inside the ESTLCam screen while on the top you see the "Tool List" window. Inside the "Tool List" you have to set the parameters of the endmill you want to use for your operations.
In the Name field set a name for your endmill e.g 3mm
In the Ø field set the diameter of your endmill. For our example we set 3mm
In the Z+ field set the Depth per Pass which is the depth increment the endmill is allowed to cut in a single pass
In the F(xy) set the feedrate
In the F(z) set the Z Axis feedrate
From the left menu select the "Hole" operation and click on the bottom left hole's border.
The properties window comes up automatically and asks you to fill a few parameters.
In the Toolpath Depth field set the maximum depth of the operation.
In the Machining Order field set the order of the operation (Number 10 indicates the first operation while the next is number 20 etc.).
After you create the operations you want in your design, click on File-->Save CNC Program and save the program's GCode.
To send the GCode to your CNC you need to install the SourceRabbit GCode Sender and follow the "How to Send GCode to your Machine" guide.
